Can the DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ, be used with Viton seals for temperatures up to +200Â°C?

Yes. The DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ can be used with Viton seals for temperatures up to +200Â°C. The product description lists Viton (fluoroelastomer) as an available seal option with a specified operating temperature range of -15Â°C to +200Â°C. Ensure you select Viton seals when ordering and confirm compatibility with your specific hydraulic fluid and dynamic conditions, but per the manufacturer data the coupling with Viton seals is suitable to +200Â°C.

Is the DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ suitable for construction machinery with high pressure fluctuations?

Yes. The DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ is suitable for construction machinery with high pressure fluctuations. It is a non-drip flat-face socket designed specifically for such applications (ISO 16028), handles hydraulic oil up to 350 bar, includes a pin to prevent accidental disconnection, and allows one-handed operation. Choose the sealing material per operating temperature: NBR (-25Â°C to +100Â°C) or Viton (-15Â°C to +200Â°C). It is interchangeable with ISO-F couplings from other manufacturers.

Does the DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ include a safety pin to prevent accidental disconnection?

Yes. The DNP PLT4 leak-free hydraulic quick coupling, carbon steel socket with GZ includes a safety pin to prevent accidental disconnection. The product description for the non-drip, flat-face socket explicitly states it features a pin for that purpose, making it suitable for construction machinery and other applications with large pressure fluctuations.
